The invention has'relation to calculating machines for performingproblems in addition, subtraction, multiplication and division, andregistering the results, and more particularly to means for cordinatingthe movementsto and from operative position of the registering and ofthe` carrying devices. The object ofthe invention is to provide improvedmeans for this purpose.

The machine is shown as' equipped with the specific selectingy means ofmy co-pending application for patent Serial No. 142,190, filed January13, 1917, of which this is a divisional application; and reference ismade thereto for such parts of the complete device as are non-essentialto the present combination.

The invention consists in the novel *construction and combinations ofparts, as hereinafter set forth.

In the accompanying drawings, ,illustrating the invention, the numeral 2designates the casing; 3 the numeral keys, arranged in a plurality ofdenominational series ;v 4 a rear transversely lshiftable carriage; 5 aseries of registering wheels upon shaft 6, said shaft having bearings insaid carriage; 8 a series of carrying dogs yor kpawls Vupon shaft V9;l() a series of selectingor differential actuating elements, oneselectingy element' for each series of numeral keys, by which they areset up, said elements being slidable upon shafts 10; 11 a series ofintermediate gear wheels upon shaft 12, said gears operating theregistering wheels and being actuated by the selecting elements and alsoby-the. carrying dogs; and 13 is an operating device or crank handleupon shaft 14, said handle operating the selecting elements and thecarrying mechanism. C l

The shafts 10 of the selecting elements are mounted in a frame 21,pivoted forwardly at 22 and adjustably supported in rear by shaft 23,said shaft carrying a cam 24, whereon bear at opposite points rollers 25of said frame, whereby,ffor each rotation ofthe shaft the frame israised from normal depressed position, raising the shafts 10 and theselecting elements into position to rotate the intermediate gears 11,upon sliding movement of said elements upon their shafts, the frame andthe selecting elements being normally in lowered position, for reasonsstated hereinafter.

The shaft of the operating handle is provided with a bevel gearconnection 26 withy yto return them to normal position. The

shaft 27 has at its rear end bevel gear connection 36 with a `transverseshaft 23, the latter shaft having spur gear connection 38 with thecarrying shaft 9, and turning the carrying shaft four times around foreach turn of the'crank handle.

In performing addition and multiplica tion, the operating handle isturned clockwise once completely, to thereby'move the frame 21 and tomove the selecting elements longitudinally upon their shafts, fromnormal lowered position, midway of the lengths of their strokes, teraised position, at the forward end of the strokes, then rearwardly tothe opposite end of the strokes, and then to return said elements tonormal position, the carrying being performed while the elements are'soreturned, in the same clockwiser movement of the handle. In performingsubtraction and division, the handle is turned counter-clockwise oncecompletely, to move said frame and to move the selecting elements fromnormal position to raised position, at the rear end of their strokes,then forwardly to the opposite end of the strokes, and then to returnthe elements to normal position, the carrying being performed as stated,while the elements are so returned.

` In order that said elements shall be returnable backwardly orforwardly, as the case may be, without actuation of the intermediategears by Ithose elements that have been axially turned, it is necessarythat, after the elements have been moved longitudinally, as stated, theyshall be lowered and then returned, so lowered, to normal position. Andinasmuch as the selecting elements are movable either rearwardly orforwardly, according to the nature of the problem, and as the carryingis performed after the elements are so moved, it is necessary that theyshall normally be located in lowered position, midway of the ends oftheir strokes.

The carrying shaft 9 is provided with a series of annular collars 42,each collar having guides 43 wherein works a transversely slidable dogor tooth S, the dogs of all of the collars being arranged spirally,entirely around the shaft in a single series.

Located between the intermediate gears 11 are reciproca-torycarryingmembers 47, pivoted at 4S and having each an arm 49, normallyextending in the path of a transverse pin 50 of a registering wheel 5,each registering wheel having a pin 50, and said member having anoppositely projectinc` arm 51, provided with a cam surface 52, adaptedto eX- tend within the path of movement of va carrying dog, there beingone member i 7 for each dog and for each registering wheel. The arms 51,when thrown pivotally by the pins 50, will cause their respective dogs,as they contact therewith in the rotation` of the carrying shaft, tomove endwise, into position to engage the intermediate gears 11. Thedogs are returned to normal position by springs 53 thereof, and thepivoted carrying members are returned to normal position by radialprojections or fingers 54 of the carrying shaft, said fingers followingthe dogs and having end cam surfaces engaging said members.

In order that, during the rotation of the registering wheels in settingup the problem, the carrying dogs shall not be moved endwise intoeffective position by those of the carrying members 47 that have beenpivotally thrown by the transverse pins of the registering wheels, andshall not, in the turning of the carrying shaft, engage and turn theregistering wheels, it is provided that the carrying shaft shall bemovable toward and away from the registering wheels, the dogs upon saidshaft being movable therewith into position for engagement with saidcarrying members, said dogs being thereby slid into active position androtating the registering wheels upon the last portion only of the turnof the crank handle. For this purpose, the carrying shaft is mounted atthe outer end of corresponding arms of bell-crank levers 59,V fulcrumedupon the shaft 23, the outer ends of the other arms of said levershaving pivotal connection with the frame 21 at G0, whereby, as the frameis raised from normal lowered position, the lever is rocked, to rock thecarrying shaft and its dogs away from the registering wheels, and as thesaid frame is lowered, after the registering wheels have been rotated insetting up the problem, the carrying shaft and its dogs are rockedtoward the registering wheels.

Means are provided to prevent the intermediate gears 11 fromoverthrowing or rotating more than one tooth when carrying, consistingpreferably of a series of bars 145, having at their forward endsdouble-beveled or V-form teeth 146, adapted to intermittently wedgebetween or mesh with the teeth of said gears, there being one said barfor each gear. The forward ends of the bars 145 are slidably supportedupon shaft 23, forked or slotted portions 147 of said bars engagingannular guide grooves of said shaft, the rear ends of the bars engagingand sliding in perforations 148 of the bar G2. rod 149has at its ends152 sliding bearings in elongated slots-150 of the frame brackets 151which carry the shafts 23 and 12, said ends being flattened in orderthat the rod may slide freely back and fort-h'without rotation.

The rod 149 is connected to the vertical A transverse corresponding bar145... The upper' or head ends 158 of the levers 154 normally bear uponthe peripheriesy of the yannularcollars 42, each said collar having acircumferential notch 159.

In this way, as the bell-crank levers 59 are operated to rock thecarrying shaft and its dogs toward the registering wheels, the levers154 and the bars 145 are moved therewith, until the forward toothed endof all of said bars mesh with the teeth of the intermediate gears. Thecollars 42 being now turned, in the carrying operation, as previouslyeX- plaincd, the notch 159 of each collar in turn, or successively, isbrought around opposite the head end of the lever 154 correspondingthereto, whereby, should any intermediate gear 11 be engaged by its pawlor finger 8, in the carrying operation, the teeth of this gear, rotatingthe space of one tooth, acting upon the forward bevel-tootlied end ofthebar 145, will push or slide said bar rearwardly,

the corresponding lever 154 'being at the same time allowed kto beturned pivotally upon rod 149, owing to the head end of the lever movingwithin the notch of the collar 42, said head end, when riding upon theperipheral surface of said collar, locking the bar 145 against slidingmovement, the forward end of the bar being engaged with the gear.

The rotation of the intermediate gear one tooth being completed, and thecollar 42 continuing to turn, the head end of the lever is immediatelypushed out of the notch 159 and the lever operated to rengage the bar145 with the intermediate gear,y this re'e'ngagement serving as a checkupon the movement of the gear, thereby preventing overthrow.
